* Note to BR-Si05, BR-Si1: Silicone brake/clutch fluid does not absorb moisture from air like ordinary brake fluid. As a result, the brake/clutch pipes, the cylinders and hoses will last much longer and you do not have to change the fluid at least once a year. Also silicone brake/clutch fluid has a sligty higher boiling point. WARNING! It is not possible to mix with other brake/clutch fluid!
